Alphabetical - I

id	Returns the identity of an object (built-in).
idexp	used to compute the expression x * (2**i) . ldexp() is the inverse function of frexp()
index	Return the index of the first occurrence of x.
inf	Returns floating-point positive infinity.
input	Returns a line from standard input (built-in).
insert	Insert a new item x into the array at position i.
int	Returns the number converted to an integer (built-in).
is	operator
isclose	Returns test
isfinite	Returns True if x is neither infinite nor NaN.
isinf	Returns True if x is a positive or negative infinity.
isinstance	Returns True if the object is an instance of the class (built-in).
isnan	Returns True if x is a NaN (not a number).
isqrt	Returns test
issubclass	Returns True if the object is a subclass of the class (built-in).
itemsize	Size in bytes of one array item.
iter	Returns an iterator object (built-in).
